Abstract: A linking mechanism includes a convex linking member and a concave linking member, which are provided to each of the chairs aligned in a left and right direction. Each of the linking members is engaged with each other so that linkage of the neighboring chairs is realized. The convex linking member includes a convex-side mounting portion, an extending portion, a notch portion, and an engaging piece. The concave linking member includes a concave-side mounting portion, an engaging projection, and a pair of engaging wall portions.

Abstract: The structure for mounting a seating body according to the present invention includes a seating body mounting portion, a leg mounting portion and a screw. The seating body mounting portion is provided to a back surface of a seating face of a seating body, and has a screw hole. The leg mounting portion is provided to a leg member, and includes a through-bore formed thereon into which a screw shaft can be inserted. The screw fixes the seating body mounting portion and the leg mounting portion. The seating body mounting portion contacts the leg mounting portion on a first region in which the screw hole is formed and on a second region which is spaced from the first region via a groove.

Abstract: A desk includes a top panel and at least one leg portion. At least one of the at least one leg portion includes a pole-shaped leg pole that supports the top panel and a leg support that has at least a part abutting a floor surface and is attached to the leg pole so as to support the leg support. The leg support includes, as devices to connect with the leg pole, a pair of sandwiching portions that abut the leg pole and are capable of sandwiching the leg pole therebetween and a fastening device that fastens and connects the pair of sandwiching portions in a state where the leg pole is sandwiched by the pair of sandwiching portions.

Abstract: A frame member includes a frame body and a sheet member. The frame body has a front surface, a back surface, an opening penetrating in a front and back direction of the frame body, and a protruding portion. One of the front surface and the back surface has an attachment groove. The sheet member constituted by a mesh-like member is stretched over the opening. The protruding portion is configured such that, after the sheet member is arranged in an area where the protruding portion is to be formed, a material for the frame body in an unsolidified state is filled and is solidified, to thereby form the protruding portion together with the frame body and fix the sheet member in a stretched state over the opening. The sheet member has reached one of the front surface and the back surface along an inner circumferential surface of the frame body.

Abstract: A movable desk includes a cam, an elevation member, a brake portion, and a guide portion. The cam rotates in accordance with a rotation of the top panel. The elevation member, including one end swingably connected to the cam, is moved downward when the top panel is rotated to the in-use position, while being moved upward when the top panel is rotated to the storage position. The brake portion is swingably connected to the elevation member and contacts a floor surface when the top panel is in the in-use position thereby fixing at least one leg portion with respect to the floor surface. The guide portion abuts the brake portion thereby to bring the brake portion into contact with a predetermined position of the floor surface.

Abstract: A table includes a pair of leg portions that has a length in a vertical direction and is hollow in shape with an opening formed at the top end thereof; a top panel that is mounted rotatably; a pair of casters, at least one such casters being provided at each of the front and the rear of a base portion of the leg portion; a contact portion that is provided on the base portion of the leg portion; and a raising/lowering mechanism that couples a movable portion, which is either one or more of the pair of casters and the contact portion, and the top panel, and switches what comes into contact with a floor surface between the pair of casters and the contact portion by raising/lowering the movable portion in accordance with a rotation of the top panel. The raising/lowering mechanism couples the top panel and the movable portion through the opening.

Abstract: A chair includes: a seat body having a seating surface which provides seating to a user; a support device that supports the seat body such that the seat body is movable along a front-to-rear direction of the chair within a predetermined range; and an urging device. When the seat body is located in an area between a front position and a first reference position, the support device supports the seat body such that the seat body is moved to the front position by own weight. When the seat body is located between a rear position and a second reference position, the urging device urges the seat body toward the front position, whereas, when the seat body is located between the second reference position and the front position, the urging device does not urge the seat body.
